Omega-3 fatty acids play a vital role in brain function. These essential fats are key components of cellular membranes in the brain and are crucial for neuronal health. Research suggests that adequate omega-3 intake can improve cognitive functions, such as memory and learning. They also exhibit anti-inflammatory properties, which may protect against neurodegenerative diseases. Foods rich in omega-3s, like fish, flaxseeds, and walnuts, have been associated with better mental health outcomes, including lower rates of depression and anxiety.
